The goal of the project this month is for students to design and build a tinfoil boat that is capable of carrying the maximum weight with the least expense, learning the scientific concept of buoyancy; incorporating the technological tool of TinkerPlots; applying engineering principles to designing and building a boat; and using mathematical knowledge of area, graphs, and data analysis. Integrating Science Technology Engineering in Mathematics (iSTEM) is the venue for ideas and activities that stimulate student interest in these integrated fields in K–grade 6 classrooms.
